Tabular corundum|Henan Sicheng Grinding Technology Co., Ltd

Tabular corundum|Henan Sicheng Grinding Technology Co., Ltd Plate corundum is a pure, sintered corundum that is completely shrunk without adding any additives such as MgO and B2O3, with a crystal structure of α-Al2O3 with coarse crystals and well-developed, and the content of Al2O3 is more than 99%. Plate-like crystal structure, small pores and more closed pores, and porosity is roughly the same as electrofused corundum, high purity, good volume stability, very small re-sintering shrinkage, used to produce refractory materials or castables after high temperature treatment has good thermal shock stability and flexural strength, but the price is higher than other alumina.

Plate corundum|Henan Sicheng Grinding Technology Co., Ltd

Tabular corundum is a fully recrystallized -AL2O3, which is batched, ground and shaped and sintered at a temperature slightly lower than the melting point of imported alumina. The crystals are staggered in a table line, which increases the mechanical strength of the particles. The closed pores are mainly evenly distributed inside and between the particles, with high bulk density, low apparent porosity, and low water absorption, which reduces the amount of liquid used in the reprocessed product
